Rule 3

Rule 4

Some nouns are always used in singular . These are uncountable nouns. We should not use article A/An with such nouns. These are -
Scenery, poetry, furniture, advice, information, hair, language. business, mischief, bread, stationery, crockery, luggage, baggage, postage, knowledge, wastage, money, jewellery, breakage etc,We can not pluralise such nouns by adding `S' or 'es'. Example It is incorrect to write sceneries, informations, furnitures, hairs.If hair is used as countable it can be pluralised : e.g., one hair, two hairs.Example I need three hairs of a black horse.

Rule 5

Some nouns have the same form in singular as well as in plural. e.g., deer, fish, crew, family, team, jury, carp, pike, trout, aircraft, counsel ,swine, vermin, etc.

Rule 6

Some nouns have plural meaning. If a definite numeral adjective is used before them they are not pluralised. e.g., pair, score. Gross , stone ,hundred, dozen, thousand. million. billion. etc.Otherwise these nouns can well be pluralised:
Dozens of women, Hundreds of people, Millions of dollars, Scores of shops. Many pairs of shoes, thousands millions etc.

Rule 7

If the same noun is repeated after preposition ,the noun will be singular.Examples
(a) Town after town was devastated.
(b) Row upon row of pink marble looks beautiful.

Rule 8

If a numeral adjective and a fraction are used with a noun, the noun is used with the numeral and the noun will be in singular.Examples
(a) He gave me one rupee and a half.
(b) She gave me two rupees and a quarter.

Avoid the following structure

Examples
(a) He gave me one and a half rupees. (Incorrect).
(b) She gave rite two and a quarter rupees. (Incorrect)If the numeral adjective and the fraction refer the multiplication, the noun be placed in the end (after the fraction) and it must be plural.Examples
(a) Your deposits has grown two and a half times within two years.
(b) My salary has increased three and a quarter times within three years.

Rule 9

Some nouns are known as common gender nouns. They can be used for either sex; Male or Female. These are called dual gender nouns. Such nouns are : teacher, student, child, clerk, candidate. advocate, worker, writer, author, leader, musician, politician, enemy, client, president, person, neighbour etc. When these are used in singular, use third person singular masculine (his) pronoun with them.Examples

(b) Every person should perform his ( not her) duty.Each. either, everyone. everybody, no one, nobody, neither, anybody are also common gender pronouns.

Rule 10
